NOTE: this issue is reportedly disputed by the Apache Tomcat team, although Red Hat considers it a vulnerability. The dispute appears to regard whether it is the responsibility of applications to avoid providing untrusted data to be deserialized, or whether this class should inherently protect against this issue [Read the notes from the security team](https://ubuntu.com/security/CVE-2013-2185?format=md#notes) ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | tomcat6 | 13.10 saucy | Ignored | | 13.04 raring | Ignored end of life | | 12.10 quantal | Ignored | | 12.04 LTS precise | Ignored | | 10.04 LTS lucid | Ignored | | tomcat7 | 13.10 saucy | Ignored | | 13.04 raring | Ignored end of life | | 12.10 quantal | Ignored | | 12.04 LTS precise | Ignored | | 10.04 LTS lucid | Not in release | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) ## Notes --- ### [mdeslaur](https://launchpad.net/~mdeslaur) upstream doesn't consider this to be a security issue, ignoring ## References * [MITRE](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-2185) * [NVD](https://nvd.nist.gov/vuln/detail/CVE-2013-2185) * [Launchpad](https://launchpad.net/bugs/cve/CVE-2013-2185) * [Debian](https://security-tracker.debian.org/tracker/CVE-2013-2185) ### Other references * *
